The unit is an original Outbound Systems Model 125. Their first production model It is used and has yellowed over the years. Comes with original power plug and receives power, it is intact but from that point I have no idea how to turn it on and test it. It has been in a box on a shelf for many years. I would be very happy with any instructions. The unit was purchased in the late 80's for my business, it was revolutionary at the time and Apple was just an infant company. It is extremely rare and certainly an intricate piece of computer history. Please see photos and any advice would be welcome. I'm open to pricing but have no idea where to start!
